In Visual Studio, After passing parameters by pointer or reference of visual studio function, the access parameter value in the function is null

Question

This is the main code where error happened:

void VRInputRemapping::DigitalInputConfig() {
bool orginput = this->curVRConfig->GetorgDigitalInput();
uint32_t deviceId = this->curVRConfig->GetcurDeviceId();
uint32_t buttonId = this->curVRConfig->GetcurButtonId();

printf("Digital orginput: %d      device:%d    butonid:%d\n", orginput, deviceId, buttonId);
vrinputemulator::DigitalInputRemapping* m_currentRemapping =new vrinputemulator::DigitalInputRemapping(true);
vrinputemulator::DigitalBinding* m_currentBinding = new vrinputemulator::DigitalBinding;
if (orginput == false) {
    m_currentBinding->type = vrinputemulator::DigitalBindingType::Disabled;
    memset(&m_currentBinding->data, 0, sizeof(m_currentBinding->data));
    m_currentBinding->data.openvr.buttonId = buttonId;
    m_currentBinding->toggleEnabled = false;
    m_currentBinding->toggleDelay = 0;
    m_currentBinding->autoTriggerEnabled = false;
    m_currentBinding->autoTriggerFrequency = 1;
    m_currentRemapping->binding = *m_currentBinding;
}
else if (orginput == true) {
    m_currentBinding->type = vrinputemulator::DigitalBindingType::NoRemapping;
    memset(&m_currentBinding->data, 0, sizeof(m_currentBinding->data));
    m_currentBinding->data.openvr.buttonId = buttonId;
    m_currentBinding->toggleEnabled = false;
    m_currentBinding->toggleDelay = 0;
    m_currentBinding->autoTriggerEnabled = false;
    m_currentBinding->autoTriggerFrequency = 1;
    m_currentRemapping->binding = *m_currentBinding;
}

    printf(" void VRInputRemapping::DigitalInputConfig()  m_currentRemapping->binding.type:%d      device:%d    buttonId:%d  remapping.data.openvr.buttonId%d\n", m_currentRemapping->binding.type, deviceId, buttonId, m_currentRemapping->binding.data.openvr.buttonId);

//<--------------------Here is the function call-------------------------------------->

this->inputEmulator->setDigitalInputRemapping(deviceId, buttonId, m_currentRemapping);

//<--------------------Here is the function call-------------------------------------->

    printf(" void VRInputRemapping::DigitalInputConfig()  m_currentRemapping->binding.type:%d      device:%d    buttonId:%d  remapping.data.openvr.buttonId%d\n", m_currentRemapping->binding.type, deviceId, buttonId, m_currentRemapping->binding.data.openvr.buttonId);

delete m_currentBinding;
delete m_currentRemapping;
Sleep(1);

}

This is the Function:

void VRInputEmulator::setDigitalInputRemapping(uint32_t deviceId, uint32_t buttonId, DigitalInputRemapping* remapping, bool modal) {
printf("VRInputEmulator::setDigitalInputRemapping   Digital orginput: %d      device:%d    butonid:%d    remapping->binding.data.openvr.buttonId%d\n", remapping->binding.type, deviceId, buttonId, remapping->binding.data.openvr.buttonId);
if (_ipcServerQueue) {
    ipc::Request message(ipc::RequestType::InputRemapping_SetDigitalRemapping);
    memset(&message.msg, 0, sizeof(message.msg));
    message.msg.ir_SetDigitalRemapping.clientId = m_clientId;
    message.msg.ir_SetDigitalRemapping.messageId = 0;
    message.msg.ir_SetDigitalRemapping.controllerId = deviceId;
    message.msg.ir_SetDigitalRemapping.buttonId = buttonId;
    message.msg.ir_SetDigitalRemapping.remapData = *remapping;
    if (modal) {
        uint32_t messageId = _ipcRandomDist(_ipcRandomDevice);
        message.msg.ir_SetDigitalRemapping.messageId = messageId;
        std::promise<ipc::Reply> respPromise;
        auto respFuture = respPromise.get_future();
        {
            std::lock_guard<std::recursive_mutex> lock(_mutex);
            _ipcPromiseMap.insert({ messageId, std::move(respPromise) });
        }
        _ipcServerQueue->send(&message, sizeof(ipc::Request), 0);
        auto resp = respFuture.get();
        {
            std::lock_guard<std::recursive_mutex> lock(_mutex);
            _ipcPromiseMap.erase(messageId);
        }
        std::stringstream ss;
        ss << "Error while setting digital input remapping: ";
        if (resp.status == ipc::ReplyStatus::InvalidId) {
            ss << "Invalid device id";
            throw vrinputemulator_invalidid(ss.str(), (int)resp.status);
        } else if (resp.status == ipc::ReplyStatus::NotFound) {
            ss << "Device not found";
            throw vrinputemulator_notfound(ss.str(), (int)resp.status);
        } else if (resp.status != ipc::ReplyStatus::Ok) {
            ss << "Error code " << (int)resp.status;
            throw vrinputemulator_exception(ss.str(), (int)resp.status);
        }
    } else {
        _ipcServerQueue->send(&message, sizeof(ipc::Request), 0);
    }
} else {
    throw vrinputemulator_connectionerror("No active connection.");
}

}

You can See the Printf I had use before and after the function call, also used in the head of the dunction,This is the output:

void VRInputRemapping::DigitalInputConfig() m_currentRemapping->binding.type:0 device:1 buttonId:32 remapping.data.openvr.buttonId: 32 VRInputEmulator::setDigitalInputRemapping Digital orginput: 0 device:1 butonid:32 remapping->binding.data.openvr.buttonId: 0 void VRInputRemapping::DigitalInputConfig() m_currentRemapping->binding.type 0 device:1 buttonId:32 remapping.data.openvr.buttonId: 32

The output in the consloe

Please provide a [mcve] and include the output of that (as text!) in your question as well. Also, as a new user here, please take the [tour] and read [ask]. — Ulrich Eckhardt, Nov 26 '21 at 06:53
As an aside, it would also make things a lot clearer if you used a consistent naming scheme for member variables, and got rid of all the usages of "this->". — cosimo193, Nov 26 '21 at 08:18
I know OpenVR is a mess, including their examples, but can clarify what's wrong or what you are trying to achieve? — Oleg Vorobiov, Dec 02 '21 at 09:41

In Visual Studio, After passing parameters by pointer or reference of visual studio function, the access parameter value in the function is null
